Tweaking Macros, Advice?

Im 175 lbs and with from quick calculations Ive been taking 350 grams of protein and about 300 grams of carbs. My fat has been stable 90 grams.

Since I’m practically maxed out on protein and carbs and I want to get to 180+, is there any harm in getting those extra calories from bumping my fat intake to 120-130-150 and downing my carbs to 200 - 250?

I am not sure if I am losing the muscle building effect of protein by having it serve as a large energy source as well.

Any pointers on tweaking would be great.

Thanks guys.

Why not just increase the fat intake and leave carbs about the the same?

Add 3 tbsp of natural peanut butter to your day in some non PWO meals. See how you do in a couple weeks.
